Abstract

A digital holography method is proposed for determination of the depth and characteristic size of fatigue damage of fluoroorganic aircraft windows. The ability of this method to determine the characteristic lateral size of surface defects of the aircraft cabin window components with a measurement error of ±15µm and the longitudinal size (depth of the surface defect) with a measurement error of up to ±100µm (for defects with characteristic lateral sizes less than 60 µm) is demonstrated. The investigation and developed model of the digital holographic camera indicate the possibility of developing the method for testing the aircraft cabin window components for surface damage with the required accuracy and estimation of its effects on flight safety.
